Rather than use pins to test the moisture content of paper pulp on the wire in the paper-making process, some paper moisture meters use special electrodes with rolling contact heads (such as delmhorst's 12-e electrode). In the paper industry the absolute moisture value in %w is preferred because one can find out very simply the water content or the hard substances by multiplication with the %-value. Moisture content determination via loss on drying commonly used moisture analysis technologies are the moisture analyzer and the drying oven in combination with a balance. Determination of absolute moisture in paper each porous material contains water in the form of vapor in larger pores and in the form of liquid in the narrow capillaries of the structure the typical reference analysis for moisture content is a karl-fisher titration, where the sample is heated up and the use of special reagents is required.
